I'm trying to figure out how a sprinkler system works that
I've recently inherited maintenance of...
I have a sprinkler control that is attached directly to the
sprinkler valve that is buried in the ground in a valve box.
(most of the sprinkler systems I've used in the past have
a central control that runs control wires to the individual
valves ) This one is a ( rainbird I think... but I didn't see
any similar designs on their website ) single zone controller
that looks like you can set up 6 different programs. It is
attached directly to the valve that it controls. There is a
LCD display that gives status information.
In the system that I have, there are two zones and two
of these controllers. One works... the LCD display shows
data and I can switch it to 'manual on' and it activates
the valve for 10 minutes. The other one does not work..
the display is dead and switching to Manual mode does not
do anything. I can turn the valve bypass knob and get the
watter flowing and spraying... the mechanical part seems
to work... its' the electrical part that is dead...
So... my general question is... do you think that this is
a battery operated controller and the battery is dead or
does power have to be coming to the controller from an
outside source ( I don't see any extra wires... but the
hole is dirty and dark... )? I'm not sure if a few D-Cell
batteries or a 9volt battery would be enough to run the
valve or if there is a outside power source that I'm not
Is anyone familiar with this kind of controller? These
controllers are in the same valve box... If they have
to run power to these... why not put the controller
somewhere else and run the control lines to the valves
instead of separate controllers?
